To oil whom'mag/ concern;

lle it known that L Josnrn R. MYERS, citizen oit the United States, and a` resident ot the city of Chicago, county of Cook,-

State of illinois, have invented certain new i :itself distenderl condition upon -mere distention thereof and is capable of' economical manufacture. 4

The .invention consists in the combinations and arrangements of parts hereinaterdesiieriloed and claimed.

The invention will be best understood by reference to the. accompanying drawingst'orn'iing; apart of this specification, and m which,

Figure l is a perspective yleyv of one forni oi" box embodying my invention shown in distended `fornoaFig. 2., a perspective View of the sameshown in `)folded condition, lrg. 3. plan 'view of the blank from which said hoi; is made, 4. perspective `View of a modified forni of construction shown in dis-l tended form, Fig. 5 a perspective vieyr of the loox shown in Fig. i in folded cond1t1 on, ilig.

Llgancl 5 is made Figs. 7, 8, 92 l0, 11, 12 13, 14 and 15 are perspective vlewsof dilierent modified forms of construction of thefhox y ".lhe form of constructionl illustrated 1n Figs.' l, 2 and 3, comprises ai box having a bottoni 16. side. walls 1'? and. end walls 18 formed integrally with each other and all from a singlehlank as shownlflllnd Walls 18 are provided at vtheir tops with inwardly turned locking ilaps 1S) secured thereto ley means of staples-20. Slits 2l are formed m each of the flaps 19 and extendedunder and partially around each of the-staples 2O thus effecting a yielding connection "between the flaps 19 and the 'corresponding en d Walls 18. The side walls 17 are provided ,With folding iiaps 22 integrally connected therewlth and also with end Walls 18', said iiaps 22 bemg creased for folding on a diagonal line as r indicated to permit ofthe wallsi? being laid flat on bottoni member 16 as indicated Specicatiou of Letters Iiatent.

in Fig. 2 or foldingl diagonally on being;- dis tended in upright positions as indicated in Fig. 1. The flaps 22 are laid loosely and ii at under the outer free ends of the flaps 19 as shown in Fig. 2. The staples .20 are passed through flaps 19 and end Walls 18 inwardly beyond the inner edges of iaps 22. By this arrangement when the box is forced into distended form the different edges 28 oi' the ilaps .22'Will drag or slide under the corresponding edges 24 of the outer free portions of the flaps 19 forcing said portions out Wardly from the corresponding walls 18 and permitting the flaps 22 to assumethe posi`- tions indicated in Fig. l., the ends oi" flaps 19Y automatically closing over the folded flap 22 and locking thebox parts in distenclefl positions through the mere act of distending' them. This construction Iinay be readily i made up in Hat form on any ordinary sta-- pling'machine and thus is capable ofeco nomical manufacture.

Sli

In the form of construction 4illustrated in Figs. 4, 5 and 6 l employ a slightiy diiEr Vferent form of corner joint.

ln this instancethe 'folded flap ends of thewalls 'lZ are severed from `the corresponding Walls 1S along the4 lines 26 and are provided with extensions 27l extending lbeyond the length of the diagonal crease therein as indicated.

'The flaps 25 are folded into the corresponding .end Walls i8 and the corresponding;l flaps 19 secured thereover by passing rivets 20 therethrough and through the extensions 217 thus effecting' a permanent connection `herirleunder .theedges 2li ou flaps 19 fore ing the free ends of ilaps i9 outwardly to permit and causeautomatic engagement of the parts as indicated in Fig. 4.

ln `the form of construction illustrated in Fig. 7 a single horizontal slit '29 isformed in eachv of the flaps 19 overeach of-the 'staples 20 thus effecting a yielding connection as before. Otherwise the construction is identical with `that illustrated in Figs. l,

.2 and 3.

the `construction illustrated 8 a horizontal slit 30 is formed in each of the flaps 19 both below" and over each of the construction is the A a'single horizontal slit 32is formed in each tionand a horizontal slit is formed in each of thel end walls 18 ae of the walls 18. under each of the staples 20.

In the construction illustrated in Figl- 11 a single horizontal slit is formed ineach of the walls 18 above each of the staples 20. In the construction. illustrated in Fig. 12 a singlehorizontal slit 5 4 is formed in each of the' end walls 18 and extending under both of the staples 20 therein.

In the form of construction illustrated in Fig. 13 but'a single staple is employed for secu-ring each of the iiaps 19 in posiof the end'walls 18'both above and under said staple and extending considerable dis-l tances to either side thereof. ln the form of construction illustrated in Fig. 1e a. vertical slit is formed in each on each side of each of the staples 20.

ln. the. form of construction 'illustratedin Fig. 15 slits areformed in both the end walls 18 and the flaps 19, the slitsin the end walls extending over and partiallyj around the staples 20 and the slits inthe'iaps 19 extending underand partially around said staples.y

The forms of construction illustrated in Figs. 7 to 15 inclusive are but a few7 of' the modifications and arrangements by means of which my invention may be successfullycarried into effect but l have selected theseas illustrations of modifications which maybe made and which will operate successfully. 415

ln each instance however. it will be observed that one or more'slits are provided in one or more of adjoining'members 18 and 19 to effect a yielding connection therebetween, such yielding connection being necessary to permit of automatic locking cooperation of the parts as above described and dispensing with vthe necessity for any manipulations yof the parte by the person distending the box. Tl1is"connection also permits of the ready yieldingof flaps 19 Without breaking under manual manipulation if employed in boxes other than automatically locking on es.

While Ihave illustrated and described various. .forms of construction for carrying my invention into effect, these are capable of variation and modification without departing from the spiritof the invention. l, therefore, vdo not wishto be necessarily limited to any specic form of construction set forth, but desire to avail myself of such locking flap and aisance varia-tions andmodiications as comewithin lthe scope of theappended claims..
